Description

Technical Field

[0001] This utility model relates to the field of zipper waterproof testing technology, specifically a zipper waterproof performance air pressure testing device. Background Technology

[0002] A zipper is a fastener that uses continuously arranged teeth to join or separate items. It is widely used in clothing, bags, tents, and other products. It consists of two straps, each with a row of metal or plastic teeth, used to connect the edges of an opening (such as the opening of clothing or a bag). A sliding element pulls the two rows of teeth into an interlocking position to close the opening. A zipper consists of teeth, a slider, and top and bottom stops (front and back stops) or locking mechanisms. The teeth are the key component, directly determining the zipper's lateral tensile strength. Generally, a zipper has two straps, each with a row of teeth, arranged alternately. The slider grips the teeth on both sides, and by sliding along the loop, the teeth on both sides can be engaged or disengaged.

[0003] Current methods for testing the waterproof performance of zippers mainly involve splashing or dripping water onto the zipper and observing whether the water can pass through. However, this method cannot adjust the water pressure, and therefore cannot demonstrate the waterproof performance of zippers under different water pressures. Utility Model Content
